CLUSTER-TOP FOR LAMPS.

Specification of Letters Patent. Patented Oct, 12, 1920.

Application filed February 26, 1920. Serial'No. 361,593.

.certain new and useful Improvements in Cluster-Tops for Lamps, of whichthe following is a specification.

It has long been a source of trouble and inconvenience to attach anumber of electric lamp sockets to the tops of standards .of

floor and table lamps especially where the lamp stands and tops are madeof wood. Various types of tops have been made, -certain of whichrequired the making of individu-al sections which were screwed togetherin order to provide a chamber into which the electric conduit wires fromthe sockets could be manipulated and joined or spliced.

One object of my present invention is to provide an improved cluster topfor electric lamps which will facilitate the connectionof the conduitwires and lamp sockets thereto. Y

Another object is to so construct my improved cluster top that it can bequickly made at a low cost and so that the same i knob which is used tosecure the sha-de to the stand will also serve to secure the sectionstogether without the inclusion of any independent screws for said latterpurpose. These objects, and other advantageous ends which will bedescribed hereinafter, I attain in the following manner, reference beinghad to the accompanying drawings in which Y Figure 1 is a sectionalelevation of my improved cluster ktopv showing thevsame in operativeVposition with electric sockets connected thereto and illustrating thearrangement of the wiring,

Fig. 2 is a sectional elevation drawn on a smaller scale than Fig. 1showing the main section of my improved cluster top and illustrating'how the structure thereof facilitates the initial insertion of theelectric conduit wires into the top so that the sockets can be easilyattached to the top by their screw threaded nipples, y

Fig. 8 a top plan view of Fig. 7.

Referring to the drawings my improved cluster top includes a mainsection `9 which 1s preferably made of wood and turned on 'a lathe so asto Yproduce an upwardly flaring head 10 at its upper end. In the presentinstance the main section 9 is made of a comparatively great length toprovide a standard 11 at its bottom which canbe attached to any form ofbase either for a table or floor lamp.

In making the main section 9, an integral tenen 12 is turned preferablyin a cylindrical form as illustrated so as to project upwardly from thesurface 13 which represents the top of the tapered head 10. A hole orcentral channel 14 is drilled centr-ally through the main section 9 fromthe bottom 15 into the flared head 10. vThis channel 14 however stops-short of the top of thehead 10, and two holes 16 and 17 are drilleddownwardly 'through the head 10 at converging angles. In drilling` theseholes 16 and 17 a part of the tenori 12 is drilled or cut away atportions which `are preferably diametrically opposite so as to provideslanting surfaces 18 and 19 which are lcontinuous from the tenon 12 intothe head 10. The holes 16 and 17 intersect or join each other within thehead so as to provide a communicating chamber 2O Vand the channel 14leads upwardly and communicates with the chamber 2O and the holes 16 and17. A screw 21 is inserted into the top of the tenon 12 and a portion 22of this screw 21 projects above the tcnon 12 andv is adapted to receivea knob 23 which has a screw threaded hole -24 into which the portion 22.of the screw 21 lits. rIhe bottom portion `of the knob 23 is made oflarger diameter than the top of the tenon 12.

A covering ring 25 has a hole 26 adapted to slidably lit the tenon 12;said covering ring at its base 27 being of such diameter as tocompletely cover the holes 16 and 17 and rest upon the top surface 13 asclearly shown in Fig. 1. The ring 25 is preferably madeof the sameheight as the tenon 12 so that its uppermost portion is flush with thetop of the tenon 12 and so that when the knob 23 is screwed in placeupon the screw 21 that said knob will normally serve to lock the ring 25in said position covering the holes 16 and 17. The outer surface of thering 25 is preferably curved or otherwise shaped to present anornamental configuration and so as to co-act ornamentally with the shapeof the flared head 10 to produce a pleasing design or shape for thecluster top. The flared head 10 has apertures 28 and 29 drilled in itssides; saidapertures extending upwardly at converging angles to provideconnection for screw threaded nipples 30 for attachment to the electriclamp sockets 31.

The construction and arrangement of the parts of my improved topfacilitates the attachment of the lamp sockets 31 and the electricconduit wires 32. It will be noted that the lapertures 28 and 29 are sopositioned that they extend in a direction vtoward therespectiveslanting surfaces 1S and 19. By thus arranging the parts, whenit is desired to attach the sockets and electric wires to the top, it ismerely necessary to insert the ends of the wires, which are respectivelyattached to the sockets, through the apertures 28 and 29 and said endsas shown at the right hand side of Fig. 2 will initially engage theslanting surface 19 and will be deflected upwardly out of the hole 17where they can be easily grasped by the hand and the wires can be pulledupwardly until the socket and nipple are in line lwith the aperture andthe socket can be easily attached to the head 10. Fig. 2 at the lefthand side shows how the wires can be pulled upwardly through one of theholes, in the present instance the hole 16, after which the socket andnipple can be attached with the nipple 30 within the aperture 28. Afterthe sockets have been attached as shown in Fig. 3, the wires canthen bebent and the free ends can be projected downwardly through the holes 16and 17 and here again the slanting surfaces 18 and 19 will serve asdeflecting means for directing Vthe ends of the wires downwardly throughthe channel 14 and outwardly through the bottom thereof, as shown inFig. 1, after which they can be Y spliced or coupledv to the feed wires.

If desired the coupling nipples 3() can be screwed inthe apertures 29before the wires are inserted and the wires can be inserted through thenipples and will act in the same manner as above described. In thisinstance the sockets Vcan be secured to the nipples in the usual manner.

It will be noted that a shade, which is usually provided with a spiderhaving a central hole therein, can be attached to my improved clustertop between the knob 23 and the top of the tenon 12 and the knob 23 willthen serve to hold the shade in position and will also prevent the shadeor the covering ring 25 from moving upwardly out of position. It will befurther noted that the holes 16 and 17 and chamber 20 are properlycovered by the ring 25 without requiring that any independent screws orother securing means be employed to holdV the ring 25 in position.

I/Vhile I have describedmy invention as taking a particular form, itwill be understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, but consider that I am atliberty to make such changes andalterations as fairly come withn thescope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure byLetters Patent is V 1.
